HD audio problem on FreeBSD 12.1 bhyve VM

[Ali Abdallah]

Hi Peter,

BTW, I got recently a T495 running current, same audio issue on FreeBSD
bhyve guests, but audio works perfectly fine on OpenSUSE 15.2.

Here is /dev/sndstat on T495

pcm0: <ATI R6xx (HDMI)> (play)
pcm1: <ATI R6xx (HDMI)> (play)
pcm2: <ATI R6xx (HDMI)> (play)
pcm3: <Realtek ALC257 (Analog 2.0+HP/2.0)> (play/rec) default
pcm4: <Realtek ALC257 (Right Analog Mic)> (rec)


Regards,
Ali
